Which speed law requires drivers to adhere to posted maximum limits?

The correct answer highlights the concept of prescribed maximum speed limits, which are legally established limits that indicate the highest speed at which vehicles may legally travel on a given portion of roadway. These limits are set in accordance with local traffic laws and are clearly posted for the public to see. Adhering to these limits is mandatory, and violations can result in penalties or fines.

Prescribed maximum speed limits play a crucial role in maintaining road safety, as they take into account various factors such as traffic density, road conditions, and surrounding environments. When these limits are posted, they provide drivers with a clear guideline that helps to enhance safety and minimize collisions.

While basic speed laws do emphasize driving at a safe speed given the conditions around the driver, they do not necessarily involve adherence to posted limits. Absolute speed limits, on the other hand, are a general category that refers to limits that must not be exceeded, but do not specify that they always have to be clearly posted/have specific numbers attached. Variable speed laws pertain to limits that can change based on time of day or conditions, and therefore would not apply in the context of fixed, prescribed maximum speed limits.
